A reanalysis of Finite Temperature SU(N) Gauge Theory

TL;DR

This paper reanalyzes finite temperature SU(N) gauge theory data using a quasi-particle model, exploring how effective mass, phase transition order, and other factors scale with N_c.

Contribution

It introduces a quasi-particle approach to reinterpret lattice data for SU(N) gauge theories at finite temperature, highlighting new insights into deconfinement and scaling behaviors.

Findings

Effective mass relates to the deconfinement transition order.

Interaction measure scales with N_c^2 - 1.

Gluon condensate and screening mass play significant roles.

Abstract

We revise the $SU(N_c)$, $N_c=3,4,6$, lattice data on pure gauge theories at finite temperature by means of a quasi-particle approach. In particular we focus on the relation between the quasi-particle effective mass and the order of the deconfinement transition, the scaling of the interaction measure with $N^2_c -1$, the role of gluon condensate, the screening mass.
